IntEnz Enzyme Nomenclature


Accepted name:
glucosamine-1-phosphate N-acetyltransferase
Other name:
acetyl-CoA:D-glucosamine-1-phosphate N-acetyltransferase
Systematic name:
acetyl-CoA:α-D-glucosamine-1-phosphate N-acetyltransferase



The enzyme from several bacteria (e.g., Escherichia coli, Bacillus subtilis and Haemophilus influenzae) has been shown to be bifunctional and also to possess the activity of EC, UDP-N-acetylglucosamine diphosphorylase.
